The US and UK need to stand up to terrorism and espouse their democratic
values "very loudly, very proudly, very clearly" says the Prime Minister.

The makeshift memorial grew in the wake of the explosions at the marathon finish line on 15 April that killed three people and injured more than 260.

Mr Cameron said the US and UK needed to stand up for their democratic principles in a bid to combat the "poisonous narrative" of terrorism.

"I think above all, we need to say very loudly, very proudly, very clearly, that we're proud to live in a country, whether it is America or Britain, that is a democracy that loves freedom, that loves diversity, that's a multi-racial country and we'll never give in to terrorists," said the Prime Minister.
